a sum of squares. What symmetric matrices correspond to these quadratic forms by f
= x' Ax?
Properties of the Transpose In Problems 39–42, either prove
the properties in general using the fact that [ a, ]T = [a, ).
or demonstrate the properties for general 3 × 3 matrices.
39. (A")T = A
40. (A + B)T = AT + BT
41. (kA) = kAT, for any scalar k
